`SPIECIIFICATIOIil' forming part of -Leutters Patent No. 279,581, dated June 19, 1888.

` Application filed January 31, 151.83. (No model.) I

To all whom t may concern,.-

4 fords, in the county of Cumberland and State of Maine, have invented a new and useful lmprovement in Pumps, of which the following is a specification, reference being had tothe accompanying drawings. i

This invention relates to double-acting comblined lift and force pumps; and it consists in certain improvements in the construction of the same, the object of which is to construct a simple and inexpensive pump of great capacity, as will be hereinafter fully described, and particularly pointed out in the claims. In the drawings hereto annexed, Figure l is a Avertical sectional view of my improved pump. Fig. 2 is a horizontal sectional view on the line w w in Fig. l, and Fig. 3 is a horizontalseetional view on the line y v/ in Fig. l.

The same letters refer to the same parts in all the figures.

A in the drawings designates the cylinder of my improved pump, and B is a channel or Vwater-passage formed vertically by the side of der A and channel B rests, packing K being interposed in order to make a tight joint. The casting comprising the cylinder A and channel B is connected with the iiange J by means of bolts, or in any suitable manner, thus securing the parts together. The cylinder A, it will be seen, registers with the passage H, and the channel B with the passage I.

L L are valves, consisting of flexible strips M, of leather, rubber, or other suitable material, upon which disks N,of metal or other rigid material, are secured. The valves L L are arranged over the mouths or passages H and I, so as to open into the cylinder A and chamber F at the lower end of the channel B,

respectively. The valves are secured in position by the ends O of the iiexible strips M being clamped between the ilange J at the upper end of the pipe G and the lower end of the casting P, which. comprises the .cylinder A and channel B. By this `construction the valves are held securely and in such a lnanner as to operate freely, and they are readily accessible for repairs.

The upperend of the channel B is connected with the cylinder A by an opening, Q., above which the cover or top plate, R, is secured, packing S being interposed in order to make atight joint. The cover R has an opening, T, for thepiston-rod U, which said'opening is surrounded by 'a threaded collar, V, to receive the packing-box XV, the upper end or edge of which is provided with a flaring iiange, X, forming an oilcup.J

The lower end of the piston-rod is screwthreaded to receive the piston or plunger Y, the construction and arrangement of which is as follows: Z and A2 are two disks or plates, the inner adjoining faces of which may be convex, as shown. The lower convex side of the upper disk, Z, has a central recess, B, and a perforation, C2, large enough to admit of its being slid upon the threaded portion of the piston-rod. The lower disk, A2, has on its upper convex side a lug, D2, partly accommodated in the recess B2, and provided "with a screw-threaded recess, El, to receive the lower end of the piston-rod. A nut, F2, is adjusted upon the piston-rod above the upper disk, Z. Between the two disks Z' and A2 packing G2 is interposed.` By tightening the nut F2 the packing may be tightened to any desired extent. The packing G2 is composed of a disk, H2, of india-rubber having annular shoulders I2 on its upper and under sides, upon which rings J 2, of leather, are placed. It will be seen that, when the rubber is compressed so as to force it outwardly against the walls of the cylinder, it carries with it the leather rings J2, which are thus made to pack the piston as tightly as may be desired.

K2 is the' water-pipe, which may be constructed of planking or in 'any suitable manner, with a iiat side, L, which is provided with two openings, M2 N2, arranged above a IOO horizontal partition, O2, and an additional opening, P2, arranged below the latter. The lower end of the curved pipe G has a flange, Q2,

which is in the saine plane as the flanges E of the collars G and D ofthe cylinder A. rlhe latter and the pipe G are secured or connected to the water-pipe K2 by means of screws or bolts R2 passing through the flanges E E and Q2 of the collars C D and pipe G, which register, respectively, with the openings M2, N2, and P2 of the water-pipe. Between the flanges E E and the pipe K2 are clamped the flexible strips S2 of valves T2, constructed exactly like the valves L, hereinbefore described, and arranged to open into the water-pipe K2. Suitable nicchanisin of any kind is to be provided for opcrating the piston or plunger.

The operation ofiny invention willbe readily understood from the foregoing description, taken in connection with the drawings hereto annexed. On the downstroke of the piston the water passes through the opening I of pipe G into the channel B, and through the opening Q into the upper end of the cylinder. At the saine time water is discharged from the lower end of the latter through the pipe or collar D. On the upstroke of the piston water enters through the pipe H, and is discharged through the pipe or collar C at the upper end of the cylinder.

I claim as iny invention. and desire to secure by Letters Patent ofthe United States- 1. The combination of the cylinder A, having flanged collars C D, the pipe G, having flange Q2 in the saine plane as the flanges E 3 shoulders on its upper and lower sides, in A which packing-rings of leather are seated, and

mechanism for forcing the clamping-'plates to- Y gether so as to compress the packing, as. set forth 3. The combination ofthe pistoni-(rod, threaded at its lower end, the disk Z, having recess4 B2 and perforation C2, the disk A2, having lug` D2, provided with screw-threaded recess E2, the packing H2 J2, and the clamping-nut F2,

all arranged and operating substantially as set forth.

7In testimony that l, claim the foregoing as my own l. have hereto affixed my signature in presence 'of' two witnesses.
